The formula is 1/2 x ( a + b ) x h
A and b are the top and bottom sides and h is always the perpendicular height.

Now replace the variables...
1/2 x (6 + 14 ) x 8.4

And then...

1/2 x 20 x 8.4 which will give you 84cm^2

Hope this helps! Anymore questions let me know :)

Shana took a test with 50 questions. She lost 2 points for each of the 5 questions she got wrong. She got all 3 extra credit que

jeka57 [31]

Answer:

She gained 5 points in overall

Step-by-step explanation:

Shana lost points for each wrong question = 2

So, She lost points for 5 wrong questions = $2 \times 5$

She lost points for 5 wrong questions = 10 points

Now, She gained points for each correct question = 5

So, She gained points for 3 correct questions = $5 \times 3$

She gained points for 3 correct questions =15

So, Overall gain = 15-10 = 5

She gained 5 points in overall

Hence the total number of points gained by her is 5 points
